The narrowerends of these folded sec- Pr an im W 1C t Q Ott e or recept e tions 9 of the paper sheet are positioned in 1S p1. Oduied superimposed relation upon each other at the 45 Fig. 2 1 s a perspective view illustrating the center of the end of the mandreL 95 rst step in the method of forming the paper After tlm Winding of the paper Sheet on man k @Produce the receptacle; the mandrel has been completed to provide a Fig. 3 is atransverse sectional view through wall either of a single thickness of paper or a the collapsible mandrel and the sectional multiplicity of superimposed laminations, a form whereby the body wall of the recepdrop of a suitable adhesive may be applied at the center of the inwardly folded sections 9 which form the bottom of the receptacle to retain said sections in their folded positions.

The collapsible mandrel 8 may be of any l L544 desired construction and the sections thereof are so formed or shaped that their outer surfaces conform to the desired longitudinal and cross sectional contour of the body wall of the receptacle. Preferably, the outer surfaces of the mandrel sections are longitudinall fluted or corrugated as indicated at 10. A ter the paper sheet has been wound upon the mandrel and the section 9 folded inwardly, a pleating or luting die 11 is then applied, said die being also of sectional form and the sections thereof having their inner faces fluted or corrugated as at 12. Thus, the body wall of the body of the receptacle will be provided with the continuous longitudinally extending 'pleats or flutes indicated at 13. One end of the mandrel 8 and the die 11 have complementary portions shaped to produce the neck 14 at the open end of the receptacle and an annular bead 15 at the lower end of said neck forming an internal groove adapted to receive the edge of a paperv sealing disc.

The die 11 is now removed and the mandrel 8 collapsed and the sections thereof removed through the neck 14 of the formed receptacle. The paper receptacle is then immersed in heated liquid paraffin, which thoroughly permeates the paper sheet, eectively closing the pores thereof and also uniting the folded sections 9 forming the bottom'of the receptacle throughout their contiguous overlapping portions. The paraffin of course, completely coats both the interior and eXterior surfaces of the paperand when the same hardens or congeals, reinforces and increases the rigidity of the walls of the receptacle.

From the foregoing description considered in connection with the accompanying drawings, the nature of my present invention and the improved method of producing the paper receptacle will be clearly and fully understood. It will be apparent that by means of this method, such paper receptacles having body walls of any desired thickness may be very rapidly and accurately formed. The receptacles may be made inquart, pint, halfpint orother sizes, and the body walls thereof will be of such rigidity that they will effectively resistall ordinary p-ressures which may be applied thereon in the usual handling of such receptacles. Since the bottom Wall of the receptacle is integrally continuous with the side wall thereof, there is no possibility of leakage as-may readily happen where the receptacle is provided with a separate bottom wall or closure connected with the body wall by a joint forming means.

I have herein shown and described an emnevertheless be understood that the essential features of the present disclosure might also be embodied in variousA other alternative forms, and I accordingly reserve the privilege of resorting to all such legitimate changes therein as may be fairly embodied within the spirit and scope of the invention 'as claimed.

I claim:

1. A method of making paper receptacles which consists in first providing an elongated rectangular paper sheet along one longitudinal edge thereof. with spaced fold creases extending inwardly from said edge, then winding said paper sheet around a mandrel to form the cylindrical body wall of the receptacle and progressively folding said longitudinal edge portion along said creases in sections inwardly over one end of the mandrel to position said sections in partly overlapping relation to each other and form the bottom wall of the receptacle, then subjecting the cylindrical receptacle wall while on said mandrel to die pressure to form longitudinally extending pleats or flutes in said wall and convert the same into final shape or form, and

i finally removing the mandrel from the receptacle and immersing the receptacle in a parafiin solution to render the Walls thereof impervious and seal the several parts of the receptacle Walls in permanently fixed relation to each other.

2. The method of making a pa er receptacle havin a.y wall consisting o a single thickness o material which consists in first forming creases along one edge of a paper blank, the adjacent creases converging inwardly and terminating at their inn-er ends in spaced relation to each other, then Winding the pa er blank around a mandrel with the crease edge of said blank projecting beyond one end of the mandrel and progressively folding the projecting part of the blan during" lthe winding operation along said creases inwardly over the end of the mandrel to position the sections between said creases in partially overlapping relation to each other, then removing the mandrel from the formed receptacle, and finally coating all surfaces of the receptacle both interiorly and exteriorly thereof with a paratlin solution to render the receptacle walls impervious and to simultaneously permanently seal said overlapping end portions of the receptacle in fixed relation to each other.
